The linker is telling you it can't find the lib that contains the Tserial functions/methods at link time. You will have to review your linker command options and ensure they include the path to the location of the missing library.

@PaulS: He/she is using an UnoR3. I think this qualifies as an "Arduino question".

I'm pretty sure that that code won't run on an Arduino. The question was strictly about some code that is to run on a PC. That it's goal is to (eventually) talk to an Arduino is irrelevant. The question was not about why the code fails to talk to the Arduino, or why the Arduino fails to respond. Those would be legitimate questions.
